Frequently Asked Questions
5 questions
Carbonite is significantly better for personal computer backup because it provides fully automatic, hands-off backup that runs silently in the background. You install it once and never think about it again. Backblaze B2 is a cloud storage platform requiring technical setup and is not designed for automatic personal device backup.
Backblaze B2 is purpose-built for developers and enterprises with a full REST API, S3 compatibility, webhooks, and integration capabilities. Carbonite lacks developer tools and is not suitable for programmatic access or cloud-native workloads. Backblaze's Q1 2026 performance benchmarks also demonstrate superior upload speeds.
Backblaze B2 costs approximately $72 annually for 1TB ($0.006/GB × 1,000GB × 12 months). Carbonite costs $99-$299 annually (flat rate) regardless of whether you backup 1TB or 100TB, making Carbonite more cost-effective for larger backups but Backblaze better for small backups under 15TB.
Carbonite offers a unique Courier Recovery service—they ship a physical hard drive with your backup data if internet recovery would take too long. Backblaze B2 only supports cloud-based recovery, which can take longer for very large datasets but is typically faster for smaller restores (under 100GB).
Yes. Many users implement a hybrid strategy: use Carbonite for automatic personal computer backup and Backblaze B2 for archival, developer projects, or integrations with cloud applications. They serve different purposes and can complement each other in a comprehensive backup strategy.
